I installed them on my Besttop highrock bumper guard and ran the wiring exactly as the instructions says. I have the brown ground wire attached to a factory ground post on the driver side and the black ground attached to a ground post on the passenger side.

The issue I have is that the minute I connect the white load wire, it sparks and blows the fuse. I check to make sure there were no frayed wires, can anyone offer advice?

I installed them on my Besttop highrock bumper guard and ran the wiring exactly as the instructions says. I have the brown ground wire attached to a factory ground post on the driver side and the black ground attached to a ground post on the passenger side.

The issue I have is that the minute I connect the white load wire, it sparks and blows the fuse. I check to make sure there were no frayed wires, can anyone offer advice?

Is the white wire ran straight to a 3 prong rocker switch? If so, unplug the wires from the switch and double check that the 12v+, load, & ground are hooked to the correct prongs. The white wire shouldn't need a bigger fuse than that 3, since it's basically just the "on" switch to the relay. It sounds like it's grounded though.

Those two driving lights draw 17 amps combined. They should ONLY be installed with an aftermarket extra-cost wiring kit that includes a relay to carry those 17 amps from the battery directly to the lights so the switch doesn't have to carry all those amperes. All major driving light manufacturers like KC, PIAA, Hella, etc. make pre-wired wiring kits that include the relay. They are pre-wired so you just plug the lights in and attach the harness to the battery and a ground connection.

Driving lights should NEVER be connected up with just a fuse and switch, they draw too many amps for that. Doing so will cause the lights to not be as bright as they should be unless you use an extra-large wiring gauge, but mainly the on-off switch is simply not designed to carry that much load... eventually the switch's contacts will burn.

The wiring harness with a relay works like below... the switch turns on the relay and the relay connects the lights to the battery.

These two wiring diagrams show slightly different ways of correctly wiring driving lights.
